REUTERS The international payment system TYME has filed a lawsuit against the National Bank of Ukraine (NBU) to invalidate the NBU&#39;s decision that cancelled its registration.

However, the company says, despite repeated requests, the regulator and the SBU did not provide it with the relevant information. The company believes that the actions by the SBU and the National Bank represented by NBU Governor Yakiv Smolii are not within the legal framework and are illegal in nature. TYME was the only international non-bank payment system in Ukraine, and before its closure, it was the leader in the Ukrainian market in 2017 and the first half of 2018, the press service said. In early 2018, TYME was recognized as a socially important payment system along with Public Joint-Stock Company (PJSC) Ukrposhta, Ukraine&#39;s state-owned postal services provider. According to the company, the NBU&#39;s decision led to the closure of all business projects of TYME as well as those of its partners, including non-residents of Ukraine. This caused negative reaction on the part of millions of users of various TYME services. TYME shareholders, partners and members, including foreign investors, suffered significant financial and reputational losses. The company says the NBU has taken a nontransparent and illegal decision, and TYME intends to protect its position in court and bring the NBU to liability, the press service said. As UNIAN reported earlier, the National Bank on June 15 announced the cancellation of registration of the TYME international payment system whose payment institution is OMP-2013 LLC Financial company. According to the regulator, the company cooperated with a Russian payment system banned in Ukraine, which poses a threat to Ukraine&#39;s national security.
